Protests erupt in Yemen as Trump visits Saudi Arabia

Demonstrators on Saturday took to the streets of Yemen’s capital, Sanaa, to protest President Donald Trump’s visit to the Saudi Kingdom. For two years, Yemen has been embroiled in a civil war between the country’s Saudi-backed government and the Houthi movement, which is allied with Iran.
